CAR-HAUL.

SPECIFICATION forming part of Letters Patent N o. 787,605, dated April 18, 1905.

' Application led November 23, 1904. Serial No. 234,019.

To all whom, t may concern:

Be it known that I, ALFRED M. ACKLIN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Car-Hauls; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to car-hauls, one of its objects being to provide an auxiliary haul adapted to take the loaded car as it comes from the main haul and carry the loaded car to the tipple or return the same when empty to be in position to be again engaged by the main haul.

A further object of my invention isto provide for the quick and automatic engagement of the cable with the car caused by the travel of the cable itself.

To these ends my invention comprises, generally stated, in conjunction with a main car-haul, an auxiliary haul at the lower' end of the main car-haul comprising a cable so arranged on a series of sheaves as to engage the loaded car as it comes from the car-haul and convey the same to the tipple, while at the same time said cable is adapted to engage the empty car as it comes from the tipple and convey the same to the car-haul to be conveyed back to the point of loading.

My invention further comprises the novel gripping means hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure 1 is a diagrammatic plan view of a car-haul embodying my invention. Fig. 2 is a like diagrammatic side view of said carhaul. Fig. 3 is a broken plan view of the auxiliary haul, showing the cable and the arrangement of sheaves. Fie. 4 is a side view of same. Fig. 5 is an enlarged section of the car and a portion of the framework of the tipple-platform, showing the manner in which the cable of the auxiliary haul engages the car. Fig. 6 is a side view of a portion of said car, showing the manner of engagement with the cable.

Like numerals indicate like parts in each of the figures.

In the drawings I have illustrated my invention in connection with a common form of car-haul, in which the endless chain 2 engages the sprocket-wheels 3 and 4 at the upper and lower ends of the haul, the arrangement being such that the loaded cars coming from the tracks 5 pass onto the lower main track 6, and their descent is controlled by the chain 2. The loaded car when it reaches the substantially level track 7 leaves the chain and passing along said track 7 to the tipple. The chain 2 after vpassing around the sprocket 4 at the foot of the haul passes back and is in such position with reference to the return-track 8 as to haul up the empty cars which have been returned from the tipple over the track 9 from the kick-back 10.

The track 7 branches 0H from the main descending track 6 of the car-haul and the car when it leaves the chain 2 is carried by the slight incline of the track 7 over into position to be engaged by the auxiliary haul, which I will now describe. This auxiliary haul consists of the cable 11, which passes around the inclined sheave 12 and thence forward and un der the inclined sheave 13, over the sheave-14, down under the sheave 15 15a, over to the sheave 16, up over the sheave 17, around the sheave 18, thence forward and around the sheave 19, back over the sheave 20, from the sheave 2() down and around the sheave 21 to the' sheave 22 on the same shaft as the sprocket-wheel 4 is mounted and from which power is derived to drive the cable. The cable then passes from the sheave 22 forward over the smaller sheave 23, thence back over` the sheave 24, thence forward under the sheave 25. The cable then passes forward around the sheave 26 on the adjustable carriage 27, which is controlled by the Y weight 28 and by means of which the cable is held taut. From the sheave 26 the cable passes over the sheave 29 and around the horizontal sheave 30. From the horizontal on its return.

sheave 30 the cable passes to the horizontal sheave 31 and under the sheave 32 to the sheave 33, up from the sheave 33 to the sheave 34, and thence to the sheave 12. By this arrangement of sheaves the cable 11 is in position with reference to the track 7 to convey the loaded cars along said track 7 to the tipple, and at the same time said cable on its return is in such position with reference to the track 9 to convey the empty cars along said track into position to be engaged by the chain 2 of the car-haul to convey the empty cars up the track 8. The same power which drives the chain 2 is in this manner employed to transmit motion to the cable 11.

The cars, which may be of the ordinary construction, are provided on one of their sides with the grippers 35. The gripper 35 comprises the arm 36, having the projection 37, with the stud 38 thereon adapted to lit within an opening 39 in the bracket 40, attached to the bottom of the car by the bolts 41. This permits of a slight rotary play on the part of the arm 36, the upper portion of said arm being held loosely within the strap 42, bolted tothe sides of the car. The arm 36 is provided with the knob 43, which is adapted to bear against the band 44, which passes around the car-body. The upper end of the arm 36 has the forked portion 45, forming the gripping-seat 46, to receive the cable 11. Gripping-jaws 47, of soft steel, are inserted within the seat 46, said jaws being fitted therein so as to form a slightly wedgeshaped recess. These jaws 46 may be formed of plates of soft steel, and when inserted in seat 46 their ends are hammered or bent over to engage the fork 45, as shown in Figs. 5 and 6.

At the lower end of the arm 36 is the shoe 48, which is adapted to move in contact with the guide-bar 49, which is supported by the weighted lever 50. This weighted lever 50 is fulcrumed at 51 to the bracket 52, secured to the frame 53. The weight 54 acts to hold the guide-bar 49 up in position to be engaged by the shoe 48, while at the same time in case of undue pressure or strain said bar 49 is adapted to yield, so as to relieve any such undue pressure or strain. There are two of these guide-bars shown in Fig. 3 of the drawings, one at the point where the cable engages the loaded car andthe other at the point where the cable engages the empty car These guide-bars act to bring the grippers into alinement with the cable in order that the cable may engage properly therewith, and when once the cable has engaged further guiding or controlling of the gripper-arms is unnecessary. By having the gripper-arms 36 mounted in the manner shown, so as to have a certain amount of rotary play, it is apparent that when the cable engages the grip and the car has passed beyond the guide-bar 49 the cable will act to When my improved car-haul is in use, the

loaded cars are carried down the track 6, being held in control by engaging the chain 2, and when the car reaches the branch track 7 it leaves the chain 2 and is carried along said branch track by gravity until the cable 11 is reached, whereupon the shoe 48 on the gripper-arm 36 will engage the guide-bar 49 and the cable 11 being supported in such position with reference to the gripping-jaws of the grip as to drop therein automatically, said gripping-jaws being brought into alinement with the cable by the travel of the shoe 48 along the guide-bar 49. When the proper engagement of the cable with the grip has been made, the shoe 48 will have passed beyond the guidebar 49, whereupon the strain on the cable occasioned by the weight of the car will act to slightly cant or twist the arm 36, which is free Yto move on its pivot 38, so that the jaws of the grip will act to bind tighter on the cable, and so insure a secure hold. The car will be carried along in this manner by the cable 11 until it reaches a point near the sheave 18 and disengages itself from the said cable, whereupon the car will pass to the dump, where its load is discharged, and will then pass into the kick-back 10, where the empty car will be shifted onto the track 9 and carried forward by gravity until it reaches the cable 11, which will again engage the gripping-jaws of the. empty car in the manner above set forth, so as to carry the empty car4 along the track 9 to the point where it will free itself from the cable and be engaged by the chain 2 to be carried up the track 8 and thence back to the mine.

By my invention l provide a simple form of car-haul which is adapted to automatically engage and disengage the cars, while at the same time only one cable is employed driven by the same power which drives the main chain 2 of the car-haul. Furthermore, the same cable acts not only to advance the loaded cars to the point of discharge, but at the same time returns ,the empty cars into position to be engaged bythe chain of the car-haul.

While l have illustrated and described my invention in connection with an auxiliary carhaul, I do not wish to so limit it, as it may be applied to other uses.

What I claim is- 1. ln a car-haul,J the combination of a cable, means for driving same, a car having a gripping device extending out from the side thereof, and means for causing said gripping IOO IIO
